Why don't you guys, instead of speculating, actually go visit the drag strip to see how much difference your weight reduction makes? It's fun to speculate that XXX lbs shaves .XXX seconds off the 1/4 mile ET, but it's more fun to see it.

I never weighed all the stuff that I took out, but it was quite a bit (in terms of quantity). All the plastic panels don't weigh all that much. The weight savings should be made elsewhere, instead of gutting. I figured that out after experimenting it for myself (wanted to see how much difference gutting the interior would make at the strip). Comparing my time slips at the track with and without full interior (and taking DA into account), I can say that interior should be left alone if your Z isn't a track car.

Here are a few pictures from when I had my interior gutted. The driver's side panel was left alone, just in case I were to get T-boned on my side (I don't want metal shards poking me). Now, this was a while ago and I didn't keep it at this state for long. I actually planned on making my DD 350Z into a DD full-time drag strip car, but it costs way too much money.

The outside looks stock except for wheels (including stock exhaust):


Inside is a different story:






I even took some plastic pieces out from the engine bay:



Here's a pic of all the stuff that I took out in one place:



You make more of a difference with a full exhaust swap with a lighter one (I had Fujitsubo Super Ti, a fully titanium y-pipe back exhaust, with resonated test pipes and a matching size y-pipe). Other things, such as draining your windshield wiper fluid, lightweight battery, taking your passenger seat out, changing the driver's seat with a lighter one, etc should be your top priority if you're into shedding excess weight.

 

You are the man! Where are you gonna put those stuff?

 

you are an idiot congrats you saved 10lbs now go to jack in the box and have a burger
(any thoughts about removing you Z badge thats couple .oz there?) o and dont forget the paint on your car

 

You are a tool. Please excuse yourself from this thread.

 

dont get asshurt buddy

 

I just got back from the track. I am VERY happy with the results. A few of my friends couldn't come out but I told them I would run slower times than before the test pipes, due to knowing ahead of time the DA was going to be TERRIBLE. I was mostly wrong.

A little background:
04/28/08 @ 12:00pm without the test pipes I ran a 13.873 @ 102.34 (I couldn't find all of my time slips from that day)

Track is around 1054ft in elevation IIRC.

It was 60 degrees 50% humidity and the baro was 30.15

Density Altitude = 1221 feet
Uncorrected 13.873 @ 102.34
Corrected 13.69 @ 103.68

Tonight on the other hand, was pretty miserable. It was very hot and sticky... I was sweating my ***** off with a helmet and not running my AC....

85 degrees, 80% humidity baro 29.86...

I ran a 13.814@103.02... I was pretty shocked...

Density Altitude = 3447 feet
Uncorrected 13.814 @ 103.02
Corrected 13.24 @ 107.31

I got 12 passes in total.... only car that beat me was a 12.0 second dragster.... ran a a stage 2 srt4 (or so the driver said), a ws6, '73 mach 1, several new and previous gen stang GT's.... several trucks... etc... I felt like a red headed step child... I was the ONLY import racing tonight... and I'm not exaggerating.... there was not a single import racing tonight other than myself.... and I was representing pretty well I may say so myself!

 

My shed looks like 3hree5ive0ero's room there....

 

How am I an idiot? How did I only save 10lbs? And no, I'm not going to remove the Z badges (there are more than 1). "O and" the paint is staying.

I'm not sure what I did to make you say those things, but it's not appreciated. Now, I'm going to be nice and ask you to apologize for your uncalled for name calling, attitude, and negativity, not to mention unwanted sarcasm. Trust me, you want to apologize (read the TOU, if you're asking why you should).


Roast,
Those are great times from you. Yea, I know exactly how those conditions feel as I have to deal with that everytime I'm at the track myself. I also know what it feels like to be racing in the only import, but beating some of these domestics (and the American muscle cars).

Looking at the timeslip, it looks like your car was really moving, especially in the back half! Almost 23 mph gain is awesome. Those times aren't half bad, neither. You could improve a little bit on the launch, but I know how hard it is to get the launch perfect on such sh1tty conditions (damn near impossible). Overall, you did great. Oh, good reaction time too.

BTW, have you weighed your car before and after the weight reduction? That way, you know for sure it was the weight reduction and not your mods. Most likely, it was a combination of your improvement in skill, additional mods, weight reduction, and maybe a little luck with the uncontrollable variables (wind, climate, track prep, etc). At any rate, congrats!


edit-
The last picture is not of my room. I left all of my crap at a friend's house while they were off the car for about 2 weeks. And on the opposite side of the room (not pictured) was his crap from his weight reduction (not much, but still something) for his M35.

 

Thanks for the kind words. Yeah my top end felt good (despite the conditions). My highest trap tonight was 103.59 (gained 23.4mph in the back half on that run )

Funny you mention the weight factor. This is going to make my head hurt. I'm confused.

In april... the scales read 2905lbs without me in it. I had about 3 gallons of gas. I rubbed my eyes, checked to make sure I was on the scales properly, and since the wind was blowing pretty hard it was flickering between 2905 and 2910.

So tonight, the scales read 3100lbs without me in it. I had about 10 gallons of gas. The test pipes were a good 30lbs reduction. The extra gas was about 40lbs added.... So I should have read about 10 pounds heavier than last time...... instead I read 185lbs heavy? What the crap??? I know for a fact that's not accurate. It doesn't make ANY sense at all....... the only thing I can imagine is the scales are seriously fubar.

 

Interesting. I'm a bit sad that I never weighed all the panels I took out. I think the scale, the first time, may have been off. 2905lbs is very light and your average "gutting" won't get you there, regardless of the model. Or, at least that's my opinion. What model do you have anyway?

I weighed my car at the track about a week ago, with the passenger seat and spare (and the 2 layers of carpet) out. I have other mods that actually weigh me down but others to save weight (contradict much? ). I gave up on making my daily driven Z into a daily driven full track Z a while back, but I still do care a little bit. Anyway, my 350Z Touring with a quarter tank of gas weighed 3180 without me (and a few mods). It should be noted that my car is heavier than a stock Z with the same parts taken out, due to certain mods.

 

O i dont know why i said that.... maybe because YOU LEFT THE DRVER SIDE!!! untouched.
If you are such a "hard core" RICER you should think about more important parts than just getting rid of half of your interior

apologise? take it as if you were a men and dont get your a$$ hurt over it learn it and move on and stop crying

 

My trunk area is that stripped out too, . You can always put the plastic back in but all of it does add up to some weight. Plus, the exposed metal on the big brace lets me attach my camera mount directly to the brace with suction.

 

I dont know what to say, this thread makes me sad :'(

gutted Z's are ugly

 

You should seriously think twice about calling anyone on this forum a ricer. Especially when your punk *** 20 year old self couldn't even afford the car.

Owned.

 

3hree5ive0ero, it's an 04.5 base model with kick plates, mud guards, spoiler/stock aero kit...

If I had an accurate scale for lower weights I would weigh everything up piece by piece, bolt by bolt.

Savings...
24lbs (battery)
30+lbs (test pipes)
70ish lbs for all rear interior/spare/tools/sound deadening (probably too conservative of an estimate)
5lbs rear wiper delete
5lbs rear speakers delete
5lbs head unit delete
2.5lbs sub bracket delete

I'd say about -150lbs so far.

When I weighed the car a long time ago with the basic rear interior delete... it was 3130 without me in it... which I thought was too heavy... since then I've stripped about 70 more lbs.... I think the tracks scales are completely fubar... I think I'll need to find some scales elsewhere....

 

 

Keep insulting a moderator and see what happens. I'm surprised you haven't been banned already.

 

The spare and tools are ~45lbs so ripping out the interior panels only netted you a 25lbs difference. A lightweight clutch and flywheel will run $750 and save you 25lbs, and a titanium exhaust can get you another 50lbs off for maybe ~$1250. There are titanium headers too that replace the cast iron ones. Gutting gives you a cheaper path to less weight, but it removes more weight from the back and without the passenger seat to balance out the weight of the driver you're just putting the car off balance even more.

 

I guess you're not the brightest of the bunch. Did you even bothered to look at what I wrote BEFORE you go to the pictures? Since, you're too stupid (literally) to go back and read, I'll post it for you.
Like I said, I PLANNED on doing so, then I stopped. I was going to go all out with weight reduction. I'd start listing them out, but you wouldn't probably wouldn't read and look for more pictures.

And who said I was a "hard core (which is 1 word by the way) RICER?" What makes me a ricer? You're the one who had the ricer exhaust - RSR (loud, not much performance gain, ugly, etc). Also, I did do other mods that lighten up the car. Just because you don't see it or know about it, it doesn't mean it was never done.

Oh yea, where's your timeslip buddy? I ran 13.2s on slicks and 13.5s on street tires. I don't need weight reduction to get great times, buddy, even if I got sh1tty climate and horrible track prep. Apparently, you don't even know the definition of a "ricer." In fact, you don't even know much about anything, seeing the way you use (or lackthereof) grammar, punctuation, spelling, etc.

BTW, have a nice long break from the forums. We don't need your trash around here.

--------------------------------------------
Roast,
It looks like you're taking this weight reduction stuff seriously. That's awesome. Any other plans to get even more weight off the car?

And as far as the scale goes, I'd say go to the track, but apparently your track scales are very inconsistent. You can also go to a truck stop and weigh your car there. I've done it before, but it'll cost you. It cost me about $8.50 I think.

--------------------------------------------
The Schroed,
I was at an exotics meet. I'm back now and he's been taken care of.

--------------------------------------------
Mostlypeaceful,
Yeah, as I mentioned, the interior panels won't get too much weight off the car. The lightweight clutch and flywheel will not only remove weight, but it's also removing rotational mass.

And I used to have a y-pipe back titanium exhaust (1st generation Fujitsubo Super Ti) and that was badass. You won't lose the said 50lbs unless you go with a full titanium single exit exhaust (JIC). And like you said, there are titanium headers, test pipes, and y-pipes, but they're way too expensive for what they do. Plus, if you break one of the welds, it's not fun getting them fixed (I know from experience). Not too many shops will touch titanium and those that do don't usually do the best jobs and/or are costly. Luckily, when I broke a few welds on my Fujitsubo Super Ti, I took it to a local professional raceshop and got it fixed for real cheap. They did a great job on it too.

And again, you're right about removing weight from mostly the rear. Unfortunately, there isn't much that we can do to take the weight off the front. However, if you're mostly into drag racing, that doesn't really matter too much, especially if you're going to be launching on slicks/drag radials.
